Maintaining Supplier Data 
Keeping your supplier data up to date is essential to avoid unnecessary costs. These are caused, for example, when bills are sent to an incorrect address. Contact details, which may change rapidly in your company due to mergers and relocations, must be properly maintained to save time and resources.
Several functions are available in the supplier data maintenance area for your supplier company, that is, on the sell side. The changes you make to your supplier master data are monitored by the purchasing company, that is, the buy side.
Maintaining Employee Data
Create Employee
Create new employees for your company by filling out the mandatory fields (those marked with an asterisk) and by accepting the terms specified in the data privacy statement. The data you have entered is automatically sent to the buy side, and you are notified when the employee data has been approved. You can then create a new user for this employee. To do so, select the employee from the list of employees and edit the user details.
List of Employees
Set a filter to display a list of certain users only by using specific search criteria. Edit, lock, unlock and delete users in your company as required.
Own Data
You can also check and maintain your own user data.
Maintaining Company Data
Attachments
You can add attachments and upload them, and also display existing attachments.
Note
Any attachments uploaded here will be available for a purchaser on the buy side as well. If you delete an attachment, it is no longer visible to the purchaser either.
Company Data
This is where you maintain your supplier master data. You are advised to have a D-U-N-S number, which is an internationally recognized common company identifier.
For more information about D-U-N-S numbers issued by Dun & Bradstreet, see http://www.dnb.com.
Certificates
Here you can review and display the certificates that have been provided by your company. In addition, you can upload certificates, provided that the purchasing company has enabled this feature. Otherwise, you only see the certificates that you have attached to certificate questions in qualification questionnaires.
If uploading certificates is enabled, you can do the following:
You can upload new certificates requested by the purchasing company.
You can upload updates for certificates that have expired or will expire soon.
The status of certificates regarding their expiration is displayed in a traffic light scheme. If a mandatory certificate is completely missing, you are alerted by a red traffic light.
Certificates that have not yet been approved by the purchaser responsible are displayed in status Pending Approval.
To maintain supplier data, the user on the sell side must have the Supplier Master Data Manager role.
